I have a form with several controls on it. As I size the form, the controls are being resized continuously. Is it possible to postpone changing the controls position until the resizing is complete?

The idea is to do the painting on Idle. This means you simple invalidate when being sized and then do your full paint when the size completes. Here is the code that you would add to your form.

bool idleHooked = false; 
protected override void OnResize(EventArgs e) 
{ 
if (!idleHooked) 
{ 
Application.Idle += new EventHandler(OnIdle); 
} 
} 
private void OnIdle(object s, EventArgs e) 
{ 
Invalidate(); 
PerformLayout(); 
if (idleHooked) 
{ 
Application.Idle -= new EventHandler(OnIdle); 
} 
}
